実験手順

To a stirred solution of 4.2 g. of 1-isopropyl-3,4,7,8-tetrahydro-4-phenyl-furo[3,2-h]quinazolin-2(1H)-one in 180 ml. of dioxane cooled to 8°±5°C. is added dropwise a solution of 2.3 g. of potassium permanganate in 100 ml. of water. After the addition is completed 1.5 ml. of formalin solution is added. The solids which precipitate are removed by filtration and the filtrate concentrated in vacuo to obtain an oil of 1-isopropyl-7,8-dihydro-4-phenyl-furo[3,2-h]quinazolin-2(1H)-one.
